The wireless device includes a short-range transceiver for communicating with an auxiliary device; a signal module for providing a mode control signal; and, a control module for controllably shifting a short-range transceiver between a power saver mode and a search mode based on the mode control signal received from the signal module. When in the search mode, the short-range transceiver is operable to search for the auxiliary device to communicate therewith. When in a power saver mode, the short-range transceiver is not operable to search for the auxiliary device. ## Claims ### Claim 1 A wireless device comprising: a short-range transceiver for communicating with a second device; a control module for controllably shifting the short-range transceiver from a second mode to a search mode, and from the search mode to the second mode, the control module configured to shift the short-range transceiver from the second mode to the search mode without sensing the second device; and a user input operable to configure the control module to provide the shifting between modes. ### Claim 2 (depends on 1) The wireless device as defined in claim 1, wherein the short-range transceiver is configured to remain inactive when in the second mode. ### Claim 3 (depends on 1) The wireless device as defined in claim 1, wherein the control module is configured to shift the short-range transceiver from the second mode to the search mode in response to a single action user input. ### Claim 4 (depends on 3) The wireless device as defined in claim 3, wherein the single action user input is a button. ### Claim 5 (depends on 1) The wireless device as defined in claim 1, wherein the wireless device comprises a detector for detecting a proximity indicator, and wherein the control module is configured to shift the short-range transceiver from the second mode to the search mode when the detector detects the proximity indicator. ### Claim 6 (depends on 1) The wireless device as defined in claim 1, wherein the control module stores at least one communication profile for communicating with the second device, and wherein the control module is operable to select a communication profile associated with the second device from the at least one communication profile for communication with the second device. ### Claim 7 (depends on 1) The wireless device as defined in claim 1, wherein the user input is voice activated. ### Claim 8 A wireless system comprising: a second device having a short-range communication module; and a wireless device having: a short-range transceiver for communicating with the second device; a control module for controllably shifting the short-range transceiver from a second mode to a search mode, and from the search mode to the second mode, the control module configured to shift the short-range transceiver from the second mode to the search mode without sensing the second device; and a user input operable to configure the control module to provide the shifting between modes. ### Claim 9 (depends on 8) The wireless system as defined in claim 8, wherein the short-range transceiver is configured to remain inactive when in the second mode. ### Claim 10 (depends on 8) The wireless system as defined in claim 8, wherein the wireless device comprises a detector for detecting when a proximity indicator is in close proximity to the wireless device, and wherein the control module is configured to shift the short-range transceiver from the second mode to the search mode when the detector detects the proximity indicator in close proximity to the wireless device. ### Claim 11 (depends on 8) The wireless system as defined in claim 8, wherein the control module is configured to shift the short-range transceiver from the second mode to the search mode in response to a single action user input. ### Claim 12 (depends on 11) The wireless system as defined in claim 11, wherein the single action user input is a button. ### Claim 13 (depends on 8) The wireless system as defined in claim 8, wherein the control module stores at least one communication profile for communicating with the second device, and wherein the control module is operable to select a communication profile associated with the second device from the at least one communication profile for communication with the second device. ### Claim 14 (depends on 8) The wireless system as defined in claim 8, wherein the user input is voice activated. ### Claim 15 A method of controlling short-range wireless communication using a short-range transceiver between a wireless device and a second device, the short-range transceiver providing a search mode and a second mode, the method comprising: shifting the short-range transceiver from a second mode to a search mode without sensing the second device and in response to a user input, and shifting the short-range transceiver from the search mode to the second mode in response to the user input. ### Claim 16 (depends on 15) The method as defined in claim 15, wherein the short-range transceiver remains inactive when in the second mode. ### Claim 17 (depends on 15) The method as defined in claim 15, further comprising: detecting when a proximity indicator is in close proximity to a wireless device; and configuring the short-range transceiver to enter the search mode when the proximity indicator is in close proximity to the wireless device. ### Claim 18 (depends on 15) The method as defined in claim 15, further comprising configuring the short-range transceiver to enter the search mode in response to a single action user input. ### Claim 19 (depends on 15) The method as defined in claim 15, further comprising: storing at least one communication profile for communicating with the second device, and configuring the short-range transceiver to select a communication profile associated with the second device from the at least one communication profile for communication with the second device. ### Claim 20 (depends on 15) The method as defined in claim 15, wherein the user input is voice activated.
